With the basic ideas sorted I have spent quite some time just playing with ideas, but as fabric samples not drawings!
The first piece used a second sari, a brighter one and used voille "sachets". A huge departure for me and interesting to stitch into it with Kantha like hand stitches.
I went back to the darker sari fabric and the silks I had brought home. I tried making square or rectangular "sachets" but they created too regular a pattern. Next I tried stitch and flip rectangles onto the sides of squares.
Now I just have to solve the issue of the lettering!
